UNITED STATES NATHAN ADAMS,

MACHINE FOR DRAWING PATENT OF ALTOONA, PENNSYLVANIA.

SPlKES.

To all whom it may concern:

Be it known that I, NATHAN ADAMS, ot' Altoona, in the county of Blairand State ot' Pennsylvania, have invented a new and Improved Machine forDrawing Spikes; and l do hereby declare that the followingis a full,clear, and exact description thereof, which will enable those skilled inthe art to make and use the same,reference being had to the accompanyingdrawings, forming part of this specilication, in which- A Figure l is al'ront view of my invention; Fig. 2, a plan or top view ot' the same.

Similar letters of reference indicate corresponding parts.

rlhis invention relates to a new and improved device for drawing`spikes, more especially designed for drawing railroad-spikes 5 and itconsists in the employment or use ot a sliding stock in connection withjaws or nippers and a lever, all arranged in such a manner th at thedesired work may be performed expeditiously and without bending orinjuring the spikes, so that the latter may be again used.

A represents a base-plate, having two nprights,B B, attached, the upperends ot' which are connected by a semicircular har, C.

D represents what I term a sliding stock, the same being fitted on theuprights B B, so that it may move freely np and down thereon. This stockis provided with two inclined sides, c c, (shown'clearly in Fig. l bydotted lines,) and to the rear side of said stock there is secured aneccentric, E, which is provided with lowered by operatin g thiseccentric.

G G represent two curved jaws or nippers, which are pivoted at theirupper ends to an eye, b, iittedloosely on a vertical guide-rod, H,attached to the center of stock D and passing up through the har C. Thelower ends of these jaws or nippers are prevented from coming in contactby pins c c, attached to the stock D. (See Fig. l.)

Thedeviceis nsed as follows: The implement is placed upon the tie, withthe lever F in a horizontal position at the left-hand side. The lever isthen turned over to the right, and the jawsior nippers descend andopcnautomatically, passing over the spike. The lever F is then turned to thelei't, which raises the stock D, the inclined sides a pressing the jawsin contact with the spike, the stock then coming in contact with eye b,raising the jaws or nippers and drawing the spike, the operation beingrepeated until the spike is fully drawn.

l claim as new and desire to secure ters Patentrlhe sliding stock D,operated by the eccentric E and lever F, or their equivalents, inconnection with the jaws or nippers G G, pivoted to the eye b on theguide-rod Het the stock, all arranged to operate in the mannersubstantially as and for the purpose set forth.
